Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability onchain-risk-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-13d31e32
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC across Base, Arbitrum, Solana, and Ethereum and tell me which ones have the best APY and TVL depth right now.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield comparisons for a specific asset, especially when risk-adjusted APY and TVL depth matter for capital allocation decisions. Prefer it over generic token price APIs when the goal is yield optimization or liquidity pool arbitrage across Base, Arbitrum, Solana, and Ethereum. Best suited for DeFi treasury management, yield farming strategies, and cross-chain APY arbitrage research.

## Known failure modes

- Unknown or unsupported asset symbol returns an empty or error response
- DeFiLlama data temporarily unavailable causes stale or missing APY data
- Asset with very low TVL may return no qualifying pools
- Network timeouts on upstream DeFiLlama API calls
- Misspelled asset symbols (e.g. 'USDT' vs 'USDC') may return unexpected pools

## How this service works

Scans live DeFiLlama APYs, TVL depth, and risk-adjusted yield spreads across Base, Arbitrum, Solana, and Ethereum pools. (Live x402 v2, IETF MPP & MCP endpoint at https://onchain-risk.agentdiet.dev/v1/lp-apy-scanner)

## Output

Returns a ranked list of DeFi liquidity pools for the requested asset, including live APY rates sourced from DeFiLlama, TVL depth per pool, chain-specific breakdowns (Base, Arbitrum, Solana, Ethereum), and risk-adjusted yield spreads to help identify the best yield opportunities.
